construction in which both wheels are journaled; to.

dispense with the steering fork usually employed in machines of this general character and to substitute therefor improved means for steering to increase the comfort of the rider and improve the facilities for controlling the machine, and to give the machine the gen.- ezsl appearance of an automobile.

i will describe a preferred embodiment of my invention and then point out the novel features in claims.

- In the accompanying drawings;-Figura 1 is a side elevation partly in section of a motor bicycle constructed in accordance with my invention; Fig. 2 is a top plan; Fig. 3 is s longitudinal horizontal section; Figs. 4 and 5 are enlarged detail views of the hub of the front wheel and part of the steei'ing devices, Fig. 4 being a side elevation .partly section and 5p sectional plan view.

The irame consists of two bars only, oneon each side of the machine, and a. connecting piece for their front ends. lhe bars are indicated by 10, and they extend substantially parallel to each other horn the driving wheel to just in the recr of the steering wheel; where as shown they are bent inwardly toward each other as at a, and then outwardly to form the curved base 1 1 of a triangular shaped front portion of the frame;

the sides 12 of which converge toward their front ends where they are dctachably secured to the connecting pi "e 13. One half the steering wheel projects into tic rrhrngulr shaped front portion and the wide end ti t-roof zrl'i'ords ample room for the rnovement of the wheel lo cllect the steering.

A pin or post 15 is firmly secured in the connecting piece 13 in the central longitudinal line of the machine, and forms a pivot about which the front wheel may be turned. A ring or collar 16 is'providcd with district rically opposite cones 17-47 which project into ball cups 18-48 screwed on the ends of the post 15, and balls 19 are interposed between the respective cones and cups. The hub 20 of the front orsteeringwheel 21 surround. the collar 16 and two sales of antifriction balls 2 are interposed between the hub 20 and ring 18, as clearly shown in Figs. 4 and 5. The wh n: can thus rotate freely on thering 16 which constitutes its axle,

but the latter is he d against rotary motion in the some direction by reason of its connection to the post 15. The ring 16 can, however, turn about the post horizontally and on account of the ball bearings between the Specification of Letters Patent. s uummnm 12.1901. Serial No. ssmoio.

ring and the hub the wheel will also turn with the ring about the post.

From the lower portion of the r'rirg 16 :1 lug or pin 22 projects on each side on which the ends of a U-shaped lever 23 are pivotallysecured to permit the rear or loop portion 23' to have vertical movement. Obviously, by moving the lever 23 to the right or left the ring 16 and whwl 21 will be turned about the post 15, and steering be thus effected.

At the converging portions a of the frame bars I pro vide a clamp plate 24 from which two bolts 25 extend downwardly through a bottom tie-piste 26 and a nut 27 is threaded on the lower end of each bolt,--engr=.ges the tie-plat: 26 and thereby clampsthe plate 24 firmly in position. From the plate 24 a post or standard 28 extends vertically and is provided at its upper end with an eye 29 through which the steering rod 30 extends.

Two braces 31 -31 are rigidly secured at their lower ends to the bsrs'10-10 from which they extend upwardly and forwardly at an inclination with their upper ends converging r\nd being joined to an eye 32 through which the steering rod 30 also exfendsf The post 28 and the braces 31 firmly sirpport the steering rod and it fits in the eyes 29 and 32 snugly but so as is turn freely therein. fastin front of the'eye 29 the rod 30 is bent downward (1' form an arm 33 which is provided with a fork 33 at its lower .end to straddle the loop end of the lever '23 and to which it is connected by a bolt or pin 33". The rear end of the steering rod 30 is provided with a hand wheel 34. I

The braces 31 serve also as supports for a foot rest or platform 35 through which levers, carrying treadles 36, 37 and 38, extend in position to be operated by the feet of the rider.

The motor is indicated by 40 and may be of any type desired such as an electric motor, gas or oil engine, etc. In thestructure shown it is intended to rotate the driving shaft 41 provided near its-outer end with a friction disk 42. This disk is splined to the shaft 41 and is adapted to be moved longitudinally on the shaft 41 to engage a ring 43, of any suitable fiber, mounted loosely I purpose of forcing it out of engagement with said ring.

. The rear wheel is indicated by 46 and is journaled in the rear end portions 'of the bus 10-10. It is provided with s lprocket wheel 47, which is connected by a chain 42 with 'a sprocket wheel 49 on the shaft 50.

On the shaft 50 a disk 51 is splined. the periphery of which engages the face of the disk- 44. A spring 52 tends normally to hold the disk 51 at its outermost position and shell-crank lever 53, connected at one end to the hub of the disk 51 and at its other end to the
